The Honda 91304-KK3-830 O-Ring (9.4X2.4) is a genuine OEM sealing component designed for the B75 portable outboard motor. As a direct Honda OEM part, it matches the original specification for bore diameter and cross-section, ensuring the seal seats and functions exactly as intended. Confirm your motor's serial number against the fitment table before ordering to be certain this is the correct O-Ring (9.4X2.4) for your unit.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact bore diameter and cross-section dimensions, so this O-ring seats and seals the way the original did
- Direct OEM Replacement — sourced directly from Honda, part number 91304-KK3-830 drops in without modification
- B75 Outboard Fitment — specified for the B75 portable outboard motor; verify your serial number against the fitment table to confirm this is the right variant for your unit
- Leak Prevention — a worn or degraded O-ring allows fluid to bypass the seal; replacing it restores a proper fluid-tight barrier and protects surrounding components from contamination or damage
An O-ring is a loop-shaped sealing component that sits in a machined groove and compresses against a mating surface to prevent fluid or gas from passing through a joint. In a marine outboard like the B75, O-rings are used throughout the fuel, lubrication, and cooling passages to maintain fluid-tight connections under the pressures and vibrations of normal operation. When an O-ring hardens, cracks, or takes a compression set over time, the seal breaks down and leaks develop — making timely replacement with the correct-size part essential to keeping the motor running cleanly.
